Jessica Simpson may be pregnant, but she hasn’t been hitting the maternity section in recent months.

“I definitely look at comfort, I buy bigger sizes,” she said at the NBC’s Television Critics Association Winter Session panel for “Fashion Star,” of how being pregnant with her first child has changed her thoughts on dressing. “I haven’t really gone to maternity clothes because I don’t really love maternity stuff.”

The singer and reality television star said she’s been so turned off by the clothing available to expectant women, she’s planning to launch her own maternity wear.

“The next thing you will see from the Jessica Simpson collection is maternity,” she said.

Beginning March 13, Jessica will serve as one of the celebrity mentors to the up and coming designers on NBC’s “Fashion Star,” from host and Executive Producer Elle Macpherson.

“The designers are from all over America, some of them are in their basements making jeans, some of them have their own businesses that are more profound,” Elle told AccessHollywood.com on Friday afternoon.

The show will feature designers competing for bids from retail buyers from Saks Fifth Avenue, Macy’s and H&M.

“They have not had a line in any of these retailers, so it’s the first opportunity for them to present their work to these powerhouses here,” Elle told Access after the panel session.

Unlike other reality shows, all of the celebrity mentors – Jessica, as well as Nicole Richie and John Varvatos – will work with all of the contestants.

“We all got to work with each designer, which I think was really helpful to them because we all bring something different,” Nicole told reporters during the “Fashion Star” session. “John is a legend, he’s an icon, and Jessica knows this business, she built her brand from the ground up, and I’m a genius (laughs), so it was really nice because we all brought different opinions. We’re not competing against each other, we’re all working together to make each designer a better version of themselves.”

The winner of each week on “Fashion Star” will have their collections debut that night online, and the following day in the winning bidder’s store. The overall winner will have their collection appear in all of the three outlets.

“It’s just as much about shopping as it [is] about fashion,” Elle said of the show.
